Any Contractors Experienced with Basement Conversions?

[Ally H.]

Hi BPers! I need some assistance with locating contractors or firms that have experience with finishing basements. Here's the background information: I have a property in San Jose, CA that has a basement. The previous owner had split up the basement into two semi-finished 1-bedroom apartments (semi-finished because the renovation was not completed up to code; i.e. no egress windows, there's moisture issues, etc.). After he was fined by the City of San Jose, he essentially deconstructed both basement apartments and removed all fixtures/cabinets/etc., except the walls.

I am interested in finishing the basement with all the necessary improvements to bring them up to code, including the necessary permits and inspections. The end goal is to have one unit for my relatives and the other one as a rental unit, but this (total of 3 units when including the main dwelling) may not be possible because the property is in a R-2 Residence District (2DU/Lot). I'll be reaching out to a planner and building inspector for their advice on this point: http://www.sanjoseca.gov/index.aspx?NID=408

I've perused the city's building website (http://www.sanjoseca.gov/building) and basement requirements (https://www.sanjoseca.gov/DocumentCenter/View/16115). The contractors that I know do not have experience with basements as they seem to require special considerations like vapor barriers, foundation grading, etc. Can anyone recommend any contractors or firms that have experience in this realm? Any advice or suggestions would be greatly appreciated. Thank you in advance!
